Bollinger Squeeze

Bollinger Squeeze is the definitive clean build of the Bollinger Squeeze: the bands recolor while volatility is compressed, a dashed box tracks the price range forming during the compression, and a triangle marks the release, the bar where price settles outside that range as the bands turn outward. Three tests are built in: Bollinger's lowest-BandWidth definition, a percentile variant, and the bands-inside-Keltner test, swappable from one input.

How to Trade the Bollinger Squeeze?

• Squeeze on: compression is a condition, not a signal. No direction is implied. The box counter shows its length.
• Bullish / Bearish Release: a close outside the squeeze range while the bands expand resolves the episode and recolors the box; both sides carry alerts.
• Faded boxes: price left the range without expanding bands. No qualifying release, so the box dims instead.
• Confirm the break: initial breaks are notorious for head-fakes; demand volume and follow-through before leaning on the release direction.

Pair it with the rest of the volatility toolkit for the aftermath.
